- Sep 21, 2020-


Multi-parameter Meter

1.Brief introduction


Multiple & portable water quality instrument LH-M900 adopts method of spectrophotometry, which supports the wavelengths of 420nm, 470nm, 520nm and 620nm, and can support multiple parameter detection.Many experiments shows that this method is simple, quick and sensitive.The instrument is small size, light and easy to carry, suitable for field and work field use.By adopting imported sensor, advanced optical system and expanding the measuring range of colorimeter, the time needed for sample dilution is saved.Test items can be freely matched according to customer requirements.The instrument has been used in various environmental protection bureau, factory waste water discharge detection, aquaculture, lake and bay detection, river regulation, laboratory scientific research detection field.
